Not regular quadrilateral

Based on their sides, all quadrilaterals can be broadly classified into two different groups: regular and irregular. A regular quadrilateral is a type of quadrilateral with four sides of equal length and four angles of equal measure, not regular quadrilateral.

A quadrilateral is a polygon that has exactly four sides. This also means that a quadrilateral has exactly four vertices, and exactly four angles. Discussions of 2-D shapes sometimes refer only to the boundary the line segments that form the edges of the figure or to the interior as well. The usual definitions of polygons, however, refer only to the line segments that form the edges of the polygon. Most of the time, context will make clear what you mean, but you should remain aware that in some cases you may need to clarify. Elementary school curricula typically have children learn the names of special subsets of quadrilaterals with particular features. Here we list the special names.

Author Taylor Hartley. Expert Reviewer Jill Padfield. Quadrilaterals are all around us — from simple squares to more complex rhombuses. Learn more about this family of shapes and what makes a quadrilateral. Plus, find out how you can find the perimeter and area of different types of quadrilaterals using easy equations. A quadrilateral is a polygon that has four sides, four angles, and four vertices. Check out each part of a quadrilateral, and reference the shape above to visualize the components:. Keep in mind, any shape that does not have four sides or four angles, or has open sides is not a quadrilateral. The quadrilateral example that you saw above is only one example out of several. Remember, as long as a shape meets all of the qualifications, it can be a quadrilateral! Here are the different types of quadrilaterals — parallelograms, squares, rectangles, and rhombuses — with picture examples and properties for each. A parallelogram has opposite sides that are parallel and equal, meaning that its opposite sides are two lines in the same plane that are equal distance from each other and never meet and they measure the same length. Its opposite angles are equal, too.

Special topics rarely in elementary or middle school Cyclic quadrilaterals: For some quadrilaterals, it is possible to pass a single circle through all four of its vertices. Quadrilateral A quadrilateral is a polygon that has exactly four sides. The square is also the name of the regular quadrilateral — one in which all sides are congruent and all angles are congruent. A square is the only regular quadrilateral known to us. Its opposite angles are equal, too. Regardless of the quadrilateral one starts with, four copies of it can be arranged to fit snugly around a single point. Reproduction in whole or in part without permission is prohibited. Quadrilaterals can be classified by whether or not their sides, angles, diagonals, or vertices have special properties. Types of quadrilaterals. Quadrilaterals are all around us — from simple squares to more complex rhombuses. Most of the time, context will make clear what you mean, but you should remain aware that in some cases you may need to clarify. Discussions of 2-D shapes sometimes refer only to the boundary the line segments that form the edges of the figure or to the interior as well.

A Quadrilateral has four-sides , it is 2-dimensional a flat shape , closed the lines join up , and has straight sides.

These special cases, called cyclic quadrilaterals, include rectangles and therefore squares and isosceles trapezoids, but also other shapes that have no special name of their own.

A regular quadrilateral is a type of quadrilateral with four sides of equal length and four angles of equal measure. The area of this rhombus is 84 cm 2. How many sides does a regular quadrilateral have? The names of many of these special quadrilaterals are also typically part of the elementary curriculum, though little else about the properties of these figures may be studied until high school. Quadrilaterals can be classified by whether or not their sides, angles, diagonals, or vertices have special properties. Area of quadrilaterals.
